[users@httpd] proper MPM and mod_php

Is using "event" MPM and mod_php ok, or should "prefork" always be used with mod_php?

Thanks

I was just looking at this yesterday on my Amazon Linux VM, and the
package-managed config for mod_php looks like this:

<IfModule prefork.c>
  LoadModule php5_module modules/libphp-5.5.so
</IfModule>

<IfModule !prefork.c>
  LoadModule php5_module modules/libphp-zts-5.5.so
</IfModule>

So it looks like there is a module that has been built with an eye
toward thread-safety. That module may be available in John's environment
as well.

Thanks,

The conventional wisdom is prefork-only if you must use mod_php.
